Abstract: An electropneumatic brake control device controls a parking brake of a vehicle with a service brake and the parking brake. It includes an electromagnetic valve device which can be supplied with compressed air from a compressed air storage via a storage connection; a parking brake signal connection for inputting parking brake signals output by an electric parking brake signaling device; and an air quantity-boosting valve device which is pneumatically controlled by the electromagnetic valve device and which has a working outlet that can be connected to a first outlet connection for at least one spring applied brake cylinder. A control air line is provided between an outlet of the electromagnetic valve device and a pneumatic control inlet of the air quantity-boosting valve device.
Abstract: An electropneumatic brake control device for controlling an air-quantity-boosting valve device which controls a parking brake of a vehicle. A valve unit is provided that has a vent valve for venting a control input of the air-quantity-boosting valve device. The vent valve has three states. In a first state, the control input of the air-quantity-boosting valve device can be vented in a throttled manner by using an aperture. In a second state, the control input of the air-quantity-boosting valve device cannot be vented. In a third state, the control input of the air-quantity-boosting valve device can finally be vented in an unthrottled manner.
